This video below features an Active Autowerke supercharged M3 we already saw in action this month. It helps put the previous video in context though as this Gen II Level III supercharged DCT E92 M3 takes on a stock BMW M S63TU twin turbo V8 motor in an F13 M6. In the previous video the M3 ran a modified F10 M5 and the race was basically even. In this video the M3 pulls fairly quickly and decisively on the stock M6.

What this goes to show is just how big of a difference there is between a stock M5/M6 S63TU and a bolt on one. Additionally, that an Active Autowerke Level III supercharged car is much stronger than a stock M6 even from a first gear roll.
